As requested, here's some more details on my yet-to-be-named movie creator.
Basically, I think that making hand-drawn movies/animations should be as easy as drawing a picture in Microsoft Paint.
The goal would be to allow you to select from a few basic shapes, such as lines, rectangles, and circles, as well as the option of adding images (JPEGS, Bitmaps, etc) for backgrounds. Ideally, you'd draw the first frame, hit next, add to the frame, move things around, hit next, continue until finished. Then hit play, and you have your animation.
One feature that would make things even more interesting would be to show a transparent view of the last frame in the current frame, so that you'd have to redraw each frame individually, but with a visual reference to the last frame that wouldn't show up when you play the movie back. This would lead to seemingly stationary objects that dance around throughout the movie, such as the effect in Waking Life, which I hope you've seen.
I'd make the source code available, and I might even make a Sourceforge project out of it if there were a few other developers interested.
The contents of the movie files would likely in XML format, and the movies would have to be played back through this program, unless enough people bitch, and I'm willing to compile the movies into executables (.exe files).
Any additional features/suggestions are welcome. I'd also like to find a place to host the files, but short of opening a GMail account for everyone to login to and download from, there must be some free file hosting services, right?
